The 19 tooth freewheel is no longer available with the planetary drive kit. Did I understand you to say that you used the stock 11 tooth on the planatary shaft and drilled and pinned it to the shaft and discarded the 19tooth freewheel sprocket? Thanks.
More pictures please?

Doug,
You are correct I used the 11 tooth sprocket on the planetary shaft and did drill and use a roll pin to anchor the sprocket to the shaft. Is the planetary still available? If not you will have to figure out another way to slow down the drive, I was considering a two step four sprocket set up when I found the planetary reducer.

Bill, It is Johneeb's design. He has intellectual property rights to it. I think I can do that with Johneeb's permission. Right now I am looking for parts and asking questions. Johneeb is the goto guy, his machine is complete. Once I get all the components I will do plans and yes digitizing them is the easy part If someone has not done them already and I have permission.I just dont know when I will start.Probably October when my little aviation gremlin is back in school. It is glider season and I am flying the glider more then the 170 this time of year. D

Johneeb,
The planetary drive and shaft are still available. $57/ each.

I have a co-worker/Instructor who owns a couple of gliders, a K-8, and a Birkfalke (?) and he's restoring the K-8 (with/despite my help/interference) and for the first time I'm excited about soaring. What an interesting group.
He belongs to the TSA here in Midlothian, TX which has a really nice gliderport and clubhouse. I'm going to look into learing to be a tow-pilot. The club has 5 Pawnees and 23 (?) club-gliders. Maybe I'll finally learn something about gliding (I've been sliding long enough.)

As for the remote tug... a news story I read this week talks about airliners being towed to the runways in lieu of running engines/taxying as a method of saving huge amounts of fuel and pollution. I wonder if remote tugs could be operated from the cockpit so that a crew could push-back, proceed to the runway, then drop the tug, start engines and takeoff. The tugs might be programmed to then take a dedicated route back to the ramp. Hmmmmn.... money there for someone....

This r/c tug we are looking at has the ability to fallow a special paint stripe on the ground so doesn’t sound too far off there George.
